Hi Folks,
There exists a proprietary data format called Format1.
A smart group of people created a non-proprietary data format called Format2.
It's used to store the same kinds of data as Format1. Of course, Format2 uses
different fields and structures.
I defined a mapping from Format1 to Format2.
I want to know if the Format1 --> Format2 mapping is correct.
Perhaps DFDL can help! Here's my idea:
- Create a DFDL schema for Format1.
- Create a DFDL schema for Format2.
- Design the DFDL schemas to produce the same XML.
- To ascertain the correctness of the Format1 --> Format2 mapping do this:
- Use the Format1 DFDL schema to parse a Format1 document to XML.
- Use the Format2 DFDL schema to parse a Format2 document to XML.
- Compare the XML's:
- If they are identical, then the mapping is correct.
- If they are within a certain tolerance, then the mapping is
correct.
E.g. of an acceptable tolerance: the Format2 XML does omits an
optional element.
- Otherwise the mapping is not correct.
Am I thinking clearly about this problem (ascertaining the correctness of the
Format1 --> Format2 mapping)?
Is the idea of using DFDL to solve this problem logical?
What are the flaws in my thinking?
